Specification of Letters Patent.

Patented July 15, 1913.

Application filed April 1, 1912. Serial No. 687,635.

To 021 7072.011). it may concern:

Be it known that 1 ANDREW R. llA'onAivD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Material-Compressing Machines, of which the following is a specification.

This invention relates to improvements in compressing machines and particularly to machines which are adapted to hold loose materials and tightly and compactly press them together to form compact masses thereof.

It is an object of the invention to provide a machine in which loose material suitable for fuel may be brought together and compressed in the form of compact sticks, the material being bound so as to maintain its compressed form.

It is a further object of the invention to provide a machine in which chips, shavings, sawdust, or the like may be compressed into solid masses and binding wires may be placed about the same and twisted to hold said masses together.-

It is a still further object of the invention to provide a machine in which material may be compressed into elongated sticks, wires being fed in knife grooves cut in sides of sticks and twisted together at the lower end of the stick of material in the machine, the said machine being provided with mecha nism for breaking the sticks at intervals for separating it into suitable lengths and with further means for twisting the broken portion of the stick with the wires upon the sides thereof so as to tightly secure the wire at the upper end of the stick.

In the accompanying drawing forming a part of this specification, Figure 1 is a front elevation of a machine constructed in accordancewith this invention. Fig. 2 is a side elevation of the said machine looking at one side thereof. Fig. 3 is a side eleva tion of the said machine looking at the opposite side from Fig. 2. Fig. 4fis an enlarged central sectional view through the forming die in which the material is'compressed.

Fig. 13 is a detail view in plan of the knives for cutting the binding wire and the cam for operating the same. Fig. 14, is a detail sectional view through adjacent parts of one ofthe dies and twisting members, showing the knives ready to cut the central portion of the twisted wire. Fig. 15 is a fragmentary perspective view showing part of the ring used in reciprocating the twisting cylinder, and one of the slots for guiding said ring.

The details and features of the invention will now be more particularly described, reference being had to the said drawing in which 15 indicates the main frame of the machine. The said frame is formed with a broad base and at a point approximately half of its height the said frame is provided with lateral extensions 16 and 17 forming a broad central platform portion for supporting the dies and cooperating mechanism.

While it will be understood that the machine may be provided with any number of forming dies and cooperating devices, yet two of such forming dies are found to 0perate advantageously upon a single machine and the drawings have been made to illustrate the machine as provided with a pair of the said forming mechanism and the invention will be described with respect thereto.

The outer ends of the platforms 16 and 17 are braced and supported by means of end standards 18 and 19. Each of said platform portions 16 and 17 is provided with an aperture 20 in which is mounted forming dies as hertofore intimated. Each of the said die forming mechanisms is preferablv constructed like the device shown and described in my previous application for patent, S. N. 636,613, filed July 3, 1911,

and is made up of a fixed die section 21 and a movable die section 22 hinged thereto at its upper end as indicated at 23. The die sections carry inner die liners 2th and 25 which together form a cylindrical passage within which the materials .to .be com pressed are forced. The said sections are also provided with groove forming blades 26 and 2? as disclosed in said prior application which form lateral grooves or kerfs 28 in the sticks of composite material 29 illustrated in Fig. 7.

The lower ends of the dies are perforated at 30 and 31 to receive binding wires 32, which are drawn from spools .33 mounted upon the adjacent framing of the machine at a suitable distance from the said dies. The wires extend through said apertures 30 and 31 into and through eyes at and 35 formed in the lower ends of blades 26 and 27, so .that the said wires are led into and properly laid in the kerfsor-side grooves 28 of the compressed material, as the said material is forced throughandoutef the dies. The lower end-of each fixed die section at rests against an adjustable abutment, usually made up of a rod 36 upon which adjustable abutment nuts 37 are mounted. The lower end of each movable die 22 is engaged by a rod 38 which is operable by a lever 39 for temporarily releasing the said movable die so as to prevent any sticking of the compressed materials Within the die mechanism. Each rod 38 is formed with a screw threaded portion iOengaging corresponding threads in the adjacent standard of the frame asclearly shown in Fig. t so that by turning it by means of the said handle 39 the rod 38 may be drawn outwardly a sulficient distance .to ease up upon the compressed material within the dies.

Each fixed die section 21 has journaled thereon a wheel d1, the periphery of which is provided with sharp serrations 42. The adjacentmeeting faces of the die-sections 21 and 22 are provided with opposing recesses 413 and 441 in their adjacentiedges to accommodate the said awheel 4:1 and permit its peripheral portion to extend into the space between the dies a'sutficientdistance to engage the compressed material forced therethrough. The said wheel will thus be caused to turn in correspondence with the downward movementof the said compressed material. One face of the wheel is provided'with'studs 45 which project from the wheel a sufficient distance to engage and operate a lever 46 which operates a feeding mechanism for the portion of the machine which separates the sticks after they have been forced downwardly .a sufficient distance, which mechanism will be hereinafter fully described.

.Below each die mechanism is mounted a mechanism for separating the sticks of ma-.

terial compressed in proper lengths and twisting the binding wire thereon. The said mechanism is made up of a stick receiving cylinder 50. Each cylinder is preferably formed in two sections having flanged upper ends, the flanges 51 thereof resting upon the upper edge of an outer inclosing cylindrical member 52. Springs 53 are interposed between the sections of the cylinders and the cylindrical member for normally holding the cylinder sections together. Screw threaded pins as are carried by the cylindrical member and engage apertures in the sections of the cylinder 50 to cause the parts to turn together and to pre vent their separation longitudinally. The said outer cylindrical member 52 is formed. in upper and lower cylindrical sections having a screw threaded engagement at their meeting ends as indicated at 54 for facilitating the assembling of the parts and for affording a cylindrical bearing around the periphery thereof at 55 .to receive and movablyengage a ring or sleeve 56, employed in raising or lowering the cylinders.

The outer cylindrical member 52 is movably mounted in a sleeve 57, which is keyed at 49 in an aperture 58 formed in a platform 59 mounted in the framing of the ma chine, said platform preferably resting on lugs formed upon the frame 15 and the end standards 18 and 19 as clearly shown in Fig. '1. A securing ring nut 61, being-employed on the lower end of said sleeve to lock it in place. Journaled upon said sleeves 57 is a bevel gear 60, the hub of said gear 60 having a bearing upon the upper surface of the platform 59. The lower end of the cylindrical member 52 is provided with a sprocket wheel 62 which is rigidly connected with said member 52 by means of set screws-63 as clearly shown in Fig. 6. The turning of the sprocket 62 is thus capable of turning the cylindrical member 52. The said sprocket wheel also limits the upward movement of the cylindrical member 52 by bearing upon the under face of the locking ring 61 when the said cylindrical member 52 is in its elevated position. The upward movement of the said cylindrical member 52 is limited by the position of the ring 56 controlled by studs 64 which are mounted upon the said ring 56. The said studs 64 carry anti-friction rollers 65 which extend into and engage a cam path 66 formed in a cam cylinder 67 The said cam cylinder 67 is provided with a base flange 68 which rests edge of the sleeve .57 as shown in Figs. 6

and 15, theenlarged base portions 70 of the studs 64 passing through said blocks 69.

The structure-ofthe parts just described is such that by rotating each bevel gear 60 each cam cylinder 67 will be turned so as to raise or depress the studs 64 and each cylindrical member 52. The said cam path 66 is preferably made with quadrantal inclined portions as shown in Fig. 3 each inclined part occupying about one-quarter of the periphery of the cam cylinder 67, so that in turning the cam cylinder from time to time its cylindrical member 52 and the material carrying cylinder 50, will be raised or depressed in due course for receiving and breaking off a portion of the stick of material compressed and also holding the same so that the said material may be turned to twist the wires around the ends thereof.

Each cylindrical member 52 is also adapted to be turned by means of its sprocket wheel 62, which is connected by a sprocket chain 71 with a driving sprocket wheel 72, mounted upon a vertical shaft 73 arranged to one side of the framing. Bearings projecting from the said framing revolubly support each shaft 73 in vertical position and a clutch member 74 is mounted upon each shaft 73 and adapted to be turned thereby when the shaft is rotated. The sprocket wheel 72 is loosely mounted on its shaft and is provided with a clutch hub portion adapted to engage the clutch member 7 4 when the sprocket wheel 72 is lowered. Each sprocket wheel is adapted to be raised or lowered by means of a lever 75 which is mounted upon a bracket 76 projecting from the platform 59. The lever 75 is secured to a rock shaft 77 mounted upon said bracket 76 so that when it is rocked the lever 75 will be caused to lower or raise the sprocket wheel 72 whereby the clutch member 74: will be capable of rotating the said sprocket wheel. An arm 78 is also secured to each shaft 77 and its free end extends toward the cam cylinder 67 and engages cams 79 secured to a cam plate 80 which is mounted upon each cam cylinder 67. The said cam cylinder 67 is turned two quarter movements or half way around between each alternate forcing of material into the dies, for forming the stick of fuel and it is desirable therefore to rotate the member 52 for twisting the wires during each half revolution of said cam cylinder 67. For this reason two cams 79 are employed for depressing each arm 78 and raising the sprocket wheels 72 out of engagement with their clutches 74 while the cylinder 52 is not being moved. At intermediate points each arm 78 will be released and permit the turning of the cylindrical member 52 by means of the sprocket chain 71 for twisting the wires. In order to insure the proper dropping of the sprocket wheels 72, an arm 81 is secured to each shaft 77 and projects outwardly therefrom carrying a weight 82 which normally tends to rock the shaft 77 so as to lower the sprocket 72.

Each cam plate 80 is preferably a horizontal circular plate having a central aperture adapted to fit over the cylindrical member 52 and resting upon the upper edge of the sleeve 57. The plate 80 is further supported by means of standards 83 which rise from the flange 68 of the said cam cylinder 67 and engage the under surface of the said cam plate 80. Securing screws are preferably employed for properly fastening the said plate 80 to the said standards. Each cam plate 80 is provided with a cam path 84 which is adapted to cause the reciprocation of oppositely arranged reciprocating knife blades 85. The said knife blades are mounted in horizontal bearings formed upon the upper end of standards 86 which are bolted at their lower ends to the platform 59. The bearing portions at the upper ends of said standards 86 project inwardly to a considerable extent over the said cam plate 80 so that bolts 87 secured to the knife blades 85 and allowed to project below the same will engage the cam path 84. The cam path is so shaped that when the cylindrical member 52 is lowered the knives 85 will be simultaneously forced inwardly toward each other so as to engage the twisted wires about centrally of the twisted portion thereof as shown in Fig. 14 and cut them so as to separate the bound portion of the stick of material from the wires still remaining in the machine.

To prevent the cam plate 67 and. the gear 60 engaging it from rising out of contact with the platform 59, brackets 88 may be secured to said platform, and provided with overhanging end portions 89 which engage the flange 68 of the cam cylinder 67, permitting its rotation but preventing its being lifted from place. Each gear 60 meshes with an actuating gear 90 which is carried by a horizontal shaft 91 mounted in a bearing 92 upon the under side of the said platform 59. Each shaft 90 is actuated from time to. time by means of a ratchet disk 93 which is secured to the outer end of the shaft 91. The said ratchet disk 93 is preferably formed with four ratchet teeth by making a corresponding number of notches in the edge of said disk 93 as clearly shown in Figs. 1 and 9 of the drawing.

Each ratchet disk 93 is adapted to be turned with a step by step movement by means of spring actuated dogs 94: and 95 which are pivotally connected with links 96 extending to a cross head 97 movably mounted upon a reciprocating rod 98. This said cross head is limited against downward movement by means of a pin 99 carried by the said rod 98. A spring 100 is interposed between the upper edge of said cross head and a collar 10.1 fastened on said rod 98.

The cross head 97 may yield upwardly when anything prevents the turning of the disk 93, as for instance the getting of a block or .chip between the die mechanism and the twisting cylinder so that the said twisting icylinder cannot be sturned temporarily. A breaking of the parts is thus guarded against. The movement of the lower ends of the din-ks v9b is guided by means of shorter links 102 which are pivoted to the lower ends of said links 96 and are also pivoted at their upperend :to the reduced end of=theshaft 91 of=the said disk 93. The outer endof said shaft also carries a bearing 1103 through which the lower end of the rod 98 passes. The dogs 94 and .95 are connected with the links 102 by springs .1014: which normally hold the outerends of said dogs .in contact withthe periphery of the disk 93. The rod 98 normally rests in the position shown in Fig. 9 so that the dog 94 is in engagement with a ratchet tooth at one side of the disk 93. An elevation of the rod 98 will cause the said dog 94: to rotate the disk 93 one quarter of a turn and the dog 95 will then come in contact with the next notch and upon the loweringof the rod 98 again will engage the proper notch to turn the disk an additional quarter turn. This through the agencyof the gears 90 and will impart two quarter turns tothe twisting mechanism so as to depress the same and raise itagain.

The upper end .of each rod 98 extends upwardly to a. point opposite the plunger mechanism which is: employed in forcing the materials into the die and engages a bearing formed in a guide plate 105 which is supported upon a bracket ,106 fastened to the frame of the machine. The :operation of each rod 98 is effected by the action of the plunger heads employed in the machine and each side of the machine is provided with such a plunger head 139 adapted to move in guides 107 secured .to the main frame. Each plunger head is provided with a plunger 108 of a proper size to fit-into the die mechanism said plunger being preferably formed as shown in Fig. 3 of the drawing. A guide hopper 109 is employed in connection with :each plunger and secured upon the die sections so as to guide the material to be compressed into the die sections. The -.plunger head 139 at each end ofthe machine is pivotally connected with a pitman 110 which extends upwardly and engages a wrist pin 111 secured to a crank disk 112. A shaft 113 mounted in bearings 1'14 upon the top of the machine frame carries the said crank disks 112. An actuating gear 115 iscentrally secured to said shaft for rotating it. The wrist pin 111 .at one end of the machine is preferably diametrisally opposite to the wrist pin at the other end of the machine so thatone plunger will be descending while the other is rising.

Any suitable driving mechanism or gear may -.be arranged to mesh with the gear 115 for operating the machine. The gear 115 is shown in the drawing as meshing with a pinion 116 which is keyed to a shaft 117 mounted 'upon suitable brackets formed upon the frame 15. The shaft 117 is pro vided with a driving pulley 118 arranged nearoneend thereof and loosely journaled thereon. The pulley may be connected by belting 119 with any suitable source of power for driving the machine. Mounted upon the-said shaft 117 is a clutch member wherebythe operation of the machine may be startedor stopped under the control of the attendant, said clutch member preferablyconsisting of a disk 120 mounted upon the shaft 117 and having friction blocks 121 upon its inner face, the said friction blocks being adapted to be forced against the adjacent side face of the pulley 118 in order to hold it rigid with respect to the said shaft 117 so that movement will be imparted therefrom to said shaft. Also mounted upon the said shaft 117 is a hub 122 fastened thereto by a key 123 and the said. hub

is provided with outwardly extending bifurcated projections within which are pivotally mounted levers 124:. The outer ends of said levers 124i are provided with adjustable bearing screws 125 adapted to engage the adjacent surface of the disk 120 so that when the other ends of the said levers are forced outwardly the bearing screws will force the disk 120 against the pulley 118. The inner ends of the said levers 12 1 are engaged by a sleeve 126, having a beveled end portion adapted to engage andspread them. A hand operated lever 127 is also mounted upon the frameof the machine and pivotallyconnected with thesaid sleeve 126 for moving it longitudinally upon the shaft 117 in operating the clutch. In order to prevent-the disk 120 from rotating with re spect to the shaft 117 the said disk 120 is provided with oppositely arranged pairs of lugs 128, between which project laterally extending-arms 129 carried by the said hub 122. The disk 120 is thus movable longitudinally of the shaft 117 but must turn with the said shaft.

Each'ofthe plunger heads 139 is provided with a laterally projecting arm 130 which projects to one side of the rod 98 upon that sideof the machine. The said arm 130 in descending is adapted to engage an abutment bracket 131, secured to the side of the rod 98 so as to carry the said rod downwardly. The rod is notched at 132 forming a shoulder 133, which is adapted to engage the upper edge of said arm 130 for lifting :the rod 98. The said rod is normally held a little to one side of the arm 130 so that the plunger may reciprocate a number of times in compressing different charges of material in the dies without reciprocating the said rod 98.

When the rod 98 is to be reciprocated for causing the turning of the twisting cylinders the said rod is moved to one side a sufficient distance to permit the notch 132 to receive the arm 130 and so that the shoulder 133 will engage said arm. In order to control the position of the upper end of each rod 98, spring pressed plungers engage the same. One of said plungers, namely 135 is mounted in a suitable housing upon the plate 105 and is provided with a rounded nose portion adapted to bear against one side of the rod 98. The said plunger 135 is normally pressed against the rod 98 by a spring 136. The plunger 135 is provided with a notch 137 adapted to be engaged by the end of a pivoted latch 138. The said latch is pivoted upon a lug on the plate 105 so as to be normally held in the position shown in Fig. 12. The bearing in the plate 105 through which the rod 98 passes is an elongated hearing as shown at 140 permitting of the rod 98 being moved laterally therein. Opposite to the plunger 135 is a similar plunger 141 also mounted in a housing on the said plate 105 and a spring 142 normally holds the said plunger against the said rod 98. The spring -136 is however preferably stronger than the spring 142, so that when the plunger 135 is released by the movement of the latch 138 out of the notch 137, the plunger 135 will force the rod 98 over in the bearing 140 against the action of the said spring 142, and in this way brings the shoulder 133 into engagement with the arm 130 of the plunger head. The latch 138 normally tends to engage the said notch 137 under the action of a spring 143 interposed between the opposite end of the latch from the notch engaging portion and the bracket 106 which supports the mechanism. IVhen the plunger 135 is moved against the action of the spring 136 the said latch will thus tend to fall into the notch 137 and lock the plunger in its retracted position. In order to release the plunger again when it is desired to have the rod 98 reciprocated, a pitman rod 144 is provided and connected at its lower end with the lever 46, while its upper end passes through an elongated guide bearing formed in a plate 145 secured to the bracket 106. The said pitman rod 144 is normally drawn upwardly by means of a spring 146 which is connected with the opposite end of the plate 145 from that through which the said pitman rod 144 passes. The said spring will thus also tend to pull the pitman rod 144 toward the opposite end of the plate 145 from the bearing through which it passes. The upper end of the said pitman rod 144 is provided with a laterally projecting detent 147 which normally overhangs the spring actuated end of the latch 138. When the latch is disconnected by the pulling downwardly of the pitman rod 144 under the action of the lever 46, it will release the plunger 135 and permit the spring 136 to force the rod 98 over in its bearing 140. At the same time the pitman rod 144 will also be forced over by means of an arm 148 rigidly clamped on said pitman rod and extending across one edge of the rod 98 so that the latch 138 will be released again and ready to engage the notch 137 when the plunger 135 is retracted. The said plunger 135 is provided with a laterally extending projection 149 which extends into the path of a plate 150 secured to one side of the rod 98. The upper end of said plate 150 is spaced from the said rod 98 a sufficient distance to pass the edge of the plate 105 and the said upper portion of said plate 150 is beveled or inclined at 151 in such a manner as to force the projection 149 to one side as the said plate engages the same. In this manner the plunger 135 is reset and latched in its retracted position as the rod 98 is elevated.

The shafts 73 at each side of the machine are operable by a. single cable 152, the said cable engaging grooves formed in pulleys 153 secured to the upper ends of said shafts 73. The cable passing around said pulleys 153 also passes about guiding pulleys 154 and 155 and thence to a grooved pulley 156 which is secured to the shaft-ing 117. In this manner the shafts 73 are continuously rotated when the machine is being driven by the shaft 117 and whenever the sprocket wheels 72 are depressed they will engage the rotating clutch members 74 and receive motion therefrom.

The operation of the machine will be readily understood from the above description and need be only generally referred to at this point. The machine is pr0vided With loose material such as shavings chips of wood and the like which are fed into the hoppers 109 upon each side of the machine. The clutch mechanism is operated for imparting movement to the shaft 117 so that the plungers 108 are reciprocated. The said plungers continually force the loose material into the dies beneath them forming a continuous compressed stick, the stick being lengthened as charges of material are continuously compressed beneath the plungers. Then a suflicient portion of the compressed stick has been forced past the wheel 41 to pull upon the pitman rod 144, the arms of the plungers will be caused to reciprocate the rods 98 thus feeding the disks 93 for two-quarters of a revolution of the cylindrical member 52 to first depress and then raise the twisting member. While the twisting member is being depressed and raised, the clutches 74: will operate the sprocket wheels 72 so as to twist the wires where the stick is broken by the depression of the cylindrical member 52. At the same time the knives will be brought together for severing the twisted wires at a point intermediate of their twisted length, leaving a slight projecting twisted portion at each end of the stick as shown in Fig. 7. As soon as the wires have been severed the completed stick will be forced downwardly by the incoming stick cbove and will drop out at the bottom of the cylindrical member 52.
